This patch fixes the back-end context switching in cases where functions
should be built with their own target contexts instead of the

Library build options from --with-multilib-list used to be processed with
*self_spec, which missed the driver's initial canonicalization. This

Yes, that is an issue that I haven't considered.
The purge rules (self_specs)
For LoongArch, the toplevel library build is always aliased to
one of the multilib variants. This patch installs it with the
actual MULTISUBDIR (instead of ".") so that the headers can be
reached by the compiler.
This patch is an update of

When multilib is enabled, the c++ header directory of the default multilib
variant needs to be linked to the toplevel since g++ does not search the
toplevel in this case.

Ok, will fix in v2.
These are exported according to the LoongArch Toolchain Conventions[1]
as a replacement of the obsolete "_LOONGARCH_{ARCH,TUNE}" macros,
which are expanded to strings representing the actual architecture
and microarchitecture of the target.

4. Using "-mno-lasx" do not cause a fallback to "-msimd=none" as
long as the -march= architecture or the default --with-simd=
setting has LSX support.
Yang Yujie (4):
LoongArch: improved target configuration interface
LoongArch: define preprocessi
The configure script and the GCC driver are updated so that
it is easier to customize and control GCC builds for targeting
different LoongArch implementations.
* Make --with-abi obsolete, since it might cause different default ABI
under the same target triplet, which is undesirable. The
